Anti-GNAI1 Antibody

The GNAI1 protein, a heterotrimeric G-protein α-subunit of the Gi family, couples numerous GPCRs to downstream effectors and inhibits adenylyl cyclase activity, shaping cAMP-dependent signaling in neuronal, immune, and endocrine tissues. This unconjugated rabbit polyclonal reagent from Antibodies.com was raised against the human GNAI1 target and detects the expected ~40 kDa band by western blot in lysates prepared from human, mouse, and rat sources. The antibody is supplied as a 1 mg/ml stock in phosphate buffered saline (PBS) at approximately pH 7.2 with 0.05% sodium azide as a preservative, packaged in a 50 µl vial. For routine western blot use, dilute into blocking buffer and titrate empirically; aliquot the stock to limit freeze-thaw events and store refrigerated at 4 °C for short-term working solutions or frozen at -20 °C for longer-term retention.
